MJUC Jr. Review: A Free Compressor by Klanghelm!

A couple year back Klanghelm released the MJUC compressor, which is actually comprised of three different plugins; The Mk1, Mk2, and the Mk3.

It is a variable-mu design compressor that is both capable of smooth leveling and also heavy pumping effects.

Now, the MJUC is premium and sells for €24, or $27, but they also decided to release the MJUC Jr., which is a combination of the Mk1 and Mk2 models featured in the MJUC.

What is clear about this compressor is that it was created with ease of use in mind, since it only features two knobs that allow you to adjust the compression as well as the output gain.

Additionally, it provides a three-way switch that lets you control controls the attack and release times of the unit, and also the slew rate of the transformers and the timing of the other parts of the circuitry, that are directly influencing the generated harmonics (saturation).

Like all Klanghelm plugins, if you want to activate the bypass, or soft bypass, you can just click on the metering window and it will bypass the signal.

In addition to this, you can view both the Gain reduction and the Output level by clicking on the “GR” or “OUT” buttons on the bottom right of the metering window.

The MJUC Jr. will work on all major DAWs, both on Windows and Mac OS, and is completely free to download at the Klanghelm Website (Link to the site).

As far as free and easy to use compressors out there, this one is my favorite since it lets you get the sound you want in little to no time, without having to deal with “option anxiety”, and not having to fiddle around with too many knobs and controls.

The file size is a total of 4.5MB, and it comes in VST, VST3, AU, and AAX formats, both 32-bit and 64-bit.

Lastly, if you’re looking for another great free compressor plugin, then check out the DC1A that they also have on their site, since it’s an incredibly easy plugin to use, featuring only two controls; input and output.
